Brief Summary:
The purpose of this study is to determine whether a single injection of Dysport with a new protocol at forearm is effective in the management of chronic lateral epicondylitis.

Condition or disease Intervention/treatment Phase
Tennis Elbow Drug: NaCl 0.9% Drug: Botulinum Toxin A Phase 3

Detailed Description:
Some studies valued the effectiveness of botulinum toxin. There is a great amount of controversy on the amount of botulinum toxin injected and the location of the injection. The purpose of the study is to compare the effectiveness of botulinum toxin injection with placebo at a new injection site at the forearm in the treatment of chronic tennis elbow unrelieved by corticosteroid injection and physiotherapy. It is a double blind randomized controlled trial.
